Atom Posted September 9, 2019 Share Posted September 9, 2019 (edited) I put together a fuel based version of the basic density based starter rocket launch scene. This scene includes a couple of additions, that I have seen posted, here on OdForum, including Fencer's smoke drag, based upon distance from origin, and hand drawn velocity curves to encourage the smoke to travel along the curve shape. The support nodes for the hand drawn velocity are shaded purple, in the DOP network. Play around with the fit values on the gas wrangle to alter damping. Increase popnet particle count to send more fuel into the system. Increase popnet life to make fuel linger, longer. ap_rocket_lift_off_fuel_based_090919.hiplc Edited September 9, 2019 by Atom 5 1 Quote Link to comment Share on other sites More sharing options...
Drughi Posted September 9, 2019 Share Posted September 9, 2019 Cool stuff! 2 Questions though. Why you use a Volume Source and gasenforceboundary for collsions? Shouldn't all this work by default? And is there a Reason you dont use OpenCl? Quote Link to comment Share on other sites More sharing options...
Atom Posted September 17, 2019 Author Share Posted September 17, 2019 (edited) You'd think so, but in my experience, it does not all work by default. I wonder why they created the node (gasenforceboundary)...? Open CL is memory bound and can fail in high memory usage scenarios. (Depends upon your hardware) Edited September 17, 2019 by Atom Quote Link to comment Share on other sites More sharing options...
Atom Posted March 26, 2020 Author Share Posted March 26, 2020 (edited) I made an attempt at "upresing" this fuel based rocket launch. Treating the original file as the a low resolution simulation does allow me to enable OpenCL. The uprezed version is on the right. A 500,000 voxel low res source drives a 4,000,000 voxel upres. ap_upres_smoke_pyro_setup_032520.hiplc Edited March 26, 2020 by Atom 4 Quote Link to comment Share on other sites More sharing options...
Mjag07 Posted April 7, 2020 Share Posted April 7, 2020 Awesome, Thanks Atom for posting this. I'm looking forward to digging in. Quote Link to comment Share on other sites More sharing options...
Noobini Posted April 7, 2020 Share Posted April 7, 2020 what's gas again ? i keep thinking fart...but i know it's not...it's an acronym for sumfin' else which keeps escaping me ...so annoying. Quote Link to comment Share on other sites More sharing options...
